COOKING-STOVE.

Specification of Letters Patent No. 4,899, dated December 22, 1846.

To all whom it may concern:

Be it known that I, J. S. SILVER, of the city of New York, in the Stateof New York, have invented a new and Improved Manner of ConstructingCooking-Stoves, which I denominate the Anthrax Stove and I do herebydeclare that the following is a full and exact description thereof.

My stove is provided with three ovens, two of them small, occupying eachside of the fire chamber, the other large occupying the whole width ofthe stove and situated in the rear of the fire chamber. The fire chamberis furnished with a horizontal grate for the anthracite, or otherfuel torest upon, and is intended to be lined with fire brick, or other badconductor of heat. I do not in- .tend to have a feeding door for thesupply of fuel but to admit this through a boiler hole immediately abovethe fire, there being a sliding, or other door for the admission of thedraft of air below the grate bars, by

which arrangement it becomes an air-tight stove. There is an ash drawerto receive the ashes when it becomes necessary to remove them, but theashes are not allowed to fall through the grate bars into this drawerduring the general use of the stove; the bottom plate of the stove hasan opening through it immediately under the grate bars, but this is tobe closed perfectly by a sliding dead plate which is to be withdrawnwhen the ashes are to be removed. Instead of the small ovens on eachside of the fire chamber, one or both of these compartments may beoccupied by a boiler.

In the accompanying drawing, Figure 1 is a perspective representation ofthe stove, the top plate Fig. 2 being removed and the front plate inpart cut away to exhibit the interior of the fire chamber; Fig. 3 is avertical section of the stove from front to back through its middle.

A A is a part of the front plate.

B, B, are the two ovens that are situated at the sides of thefire-chamber C O, which chamber as above remarked is intended to belined with fire brick, but this lining is not represented in thedrawing.

D D are the grate bars, and E is one of the small oven doors.

F is the sliding door or register for the admission of air to the fire.This may be constructed in any of the known modes, and is made to fitvery closely.

G is the ash drawer; a a is the sliding dead plate which closes anopening made,

above the ash drawer, in the bottom plate I) b of the stove.

H Fig. 3 is the large oven in the rear .of the fire chamber; 0 0 beingthe top plate of sa1d oven. This oven is surrounded at its top and sidesby a flue space I, I.

J, J, Fig. l are draft openings in the back plate of the fire chamber toadmit the heated air from the fire chamber to pass into the flue spaceabove the top plate 0 a of the rear oven. 7

ICK is a partition plate that divides this flue space into twocompartments 0 0 and c a this partition is furnished with a sliding door(Z (Z to allow of a direct passage when necessary to the exit pipe L.There is a partition 6, 6, Fig. 3, that extends down in the end fiuespaces I, nearly to the bottom plate N, of the oven, said platesextending out so as to close the fiue spaces I, and I.

The space I under the large oven is not i usually form of sheet ironpreferring this to cast iron, having found stoves so constructed tooperate better than those with side plates of cast iron; the top plate Imake of the latter material.

Having thus fully described the manner in which I construct my anthraxcooking stove, what I claim therein as new and desire to secure byLetters Patent is The special arrangement and combination of therespective parts thereof, as herein set forth; that is to say, I claimthe combining of the two ovens or boiler spaces B, B, situated on thesides of the fire chamber, with the rear oven H, the draft from the firechamber descending and passing under the partition plates e, e, on itsway to the exit pipe; and the space I under the rear oven being heatedby means of the heated air from the air chamber 0, under the fire grate,the whole being constructed substantially as herein set forth.
